Fire Hydrant Pressure Reducing Valve

Pressure Reducing Valve

Pressure reducing valve is used to reduce the pressures above the required pressure in the system. After the desired design pressure is obtained by hydraulic calculations, hydraulic calculations are made in other areas. Excessive pressures will be achieved in critical zones with the fire pump purchased at the maximum pressure and flow rate required in all these areas. The pressure reducing valve is used for setting these overpressures. Manometers must be installed in front of and behind the pressure reducing valve. Relief valve must be used by the outlet of the pressure reducing valve not less than ½ Basınç. Relief Valve adjustment pressure cannot exceed 12.1 bar.

Advantages; By adjusting the water pressure, it increases the material life of the equipment in the system. In addition , according to the hydraulic calculation in the sprinkler installation, the pressure reducing valve and the water in the water tank is prevented from ending earlier.
